until poser 8 comes out, try pj's (or somebody's) idea, which may simulate the fx of an area lite: an array of spots with narrow angle, nearly contiguous to each other, equidistant from plane of illum. object, and pointed at object (as a group, not individually) by pointing them at something very far behind obj.  one could also try an area lite using a posersurface with GI activated, but users seem unwilling to try GI in poser until the next version.
